PICK.

SPECIFICATION forming part, of Letters Patent No. 249,311, dated November 8, 1881.

Application led July 22, 188].. (Model.) I

To all whom 'it may concern Be it known that I, JOSEPH C. (BEAMER, of Leadville, in the county of Lake and State of Colorado, have invented certain new and use- `ful Improvements in Picks, of which the following is a specification.

`My invention relatesto mining-picks; and it consists in the particular means by which the wedge is prevented from jarring out, and in a peculiar construction ot' handle-socket, all as hereinafter described, and pointed out in the claim.

In the accompanying drawings, Figure l is a plan view of the pick and handle, the socket being shown in section. Fig. 2 is a cross-section taken on line a; x ot' Fig. l. Fig. 3 is a side elevation ot' thc socket with the handle and. pick removed, and Fig. etis a perspective view of the wrench.

the handle, and C the socket-head.

The pick maybe of any desired length and curvature, and may have any form of points..

Similar letters of reference indicate corresponding parts.

In the drawings, A represents the pick,`B

In the center of its length, on the under side, is formed the concave, conical, or double-inclined seat c, which fits over the correspondingly-shaped, or rather roof-shaped, rest c, formed in the horizontal pick-socket or eye d, formed through the socket-head. When the pickis in place in the socket-head itis secured there preferably by the wedge F. In the end of the socket-head is placed the set-screw h, which may be turned into the eye or picksocket the proper distance before the wedge is driven in, or it maybe tightened upon the wedge afterward, as desired. This screw is of great advantage in removing the wedge for removing the pick from the socket-head.

The socket-head O should be made of malleable iron or cast-steel, and the `handle-eye e should be enlarged at the inner end, as shown at e in Fig. 2.

In securing the handle and socket-head to` gether `the wedge b should Erst be inserted a short distance into the end of the handle, and then the handle and wedge placed in the handle-socket and the handle driven home upon the wedge b, which will cause the end of thehandle to he spread into the enlarged por,

a follower swiveled to the end offa thu xn lli-screw,

or by a key driven through the socket, or by a spring-key; but

VVhatIclaimasnew and of my i'nventionis The combination, with the wedge F `and screw h, ofthe socket-head C, having in the eye d a roof-shaped rest, c, to fit a corresponding recess in the pick, and in the fronta hole for the reception ofthe threaded shank of screw, and an enlarged cavity to receive the screwhead, as shown and described, whereby the screw works in threads of the socket-piece, and 7 5 its head is sunk below the front surface to prevent the wedge from jarring out.
